    hi.
    
 
    I want to output sweeping sine frequency in TTL voltage levle using AD9102. The datasheet is so vague that i can just output constant voltage.Is there anyone who can help me fix this:
    
 
    Output frequency range: 20kHz to 30kHz, 1kHz step;
    
 
    Number of cycles:10 cycles/frequency point. 
    
 
                                                                                Best regards!

      Hi -
      
 
      The AD9102 output is a current up to 8ma. The output compliance range is -0.5V to +1.0V. The maximum output voltage of the AD9102 is AVDD + 0.3V. To get to TTL levels you would need to follow the AD9102 with an amplifier.
      
 
      You can use the SRAM to store a list of tuning words for the on chip DDS. The tuning resolution of the DDS is 10.8hz at 180Mhz CLKP/CLKN.
      
 
      Thanks,
